A Dynamic Reservoir Modeling Approach Using the Gerg-2008 Equation of State for CCUS Projects
View through CrossRef
A dynamic reservoir model is employed to assess the efficacy and stability for for Carbon Capture, Utilization, and Storage (CCUS) projects. The GERG-2008 EoS is the industry standard for calculating the thermodynamic properties of gas mixtures including carbon dioxide (CO2) and its mixtures. The lack of ability to use it in modern dynamic reservoir simulators was a significant limitation for CCUS projects until this work appeared. This study aims to show the accuracy and reliability of the GERG-2008 Equation of State (EoS) in predicting the properties of CO2 for CCUS simulations
A simulation is carried out to validate the predictive capabilities of various EoS under varying reservoir conditions, including pressure, temperature, and flow rates. Key performance indicators are employed to evaluate the GERG-2008 EoS, providing data inportant for enhancing the efficiency and safety of future CO2 sequestration projects. The results indicate that the GERG-2008 EoS exhibits a high degree of accuracy in predicting the physical properties of CO2, which is inportant for CCUS projects. The GERG-2008 EoS consistently outperformed classical EoS models in predictions for CO2 supercritical condition properties and heat exchange parameters. Comparative analysis of GERG-2008 with other classical EoS models revealed significant improvements in both the efficiency and safety of hypothetical CO2 sequestration projects. This paper introduces a new approach by employing the GERG-2008 EoS in a dynamic reservoir simulator for modeling CO2 storage in aquifers. This approach promises to improve the efficiency and safety margins of future underground carbon storage projects, thereby offering more stable solutions for CCUS projects. The methodology involves calculations of fluid properties during all technical process modeling during object live cycle.
One of the key attributes of CO2 in the context of CCUS is its ability to exist in a supercritical state. At pressures above 73.8 bar and temperatures above 31.1°C, CO2 transitions into a supercritical fluid, exhibiting properties that are neither purely gas nor liquid. This unique phase possesses several benefits and challenges relevant to storage and operational strategies in CCUS:
